Embodiment Construction

[0075] As mentioned above, in the prior art, new words are added to the dictionary manually. Adding new words manually is prone to omissions; due to the limitation of manual processing speed, the efficiency is low; the maintenance cost of the dictionary is also pushed up by labor costs.

[0076] In the embodiment of the present invention, the computer processes the corpus, unifies the corpus into a format suitable for the computer new word discovery process, generates candidate data strings, and sets appropriate conditions to screen the candidate data strings to discover new words. Discovering new words based on computers can improve the efficiency of dictionary updating, avoid omissions, and ensure the accuracy of dictionary updating.

[0077] In order to make the above objects, features and beneficial effects of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawi...

Abstract

Provided are dictionary updating method and apparatus. The dictionary updating method comprises: performing preprocessing on a received corpus to obtain text data; performing line segmentation on the text data to obtain sentence data; performing word segmentation on the sentence data according to individual words contained in a basic dictionary, so as to obtain word data after word segmentation; performing combination processing on the adjacent word data after word segmentation, so as to generate a candidate data string; performing determination processing on the candidate data string to discover a new word; and if the new word is discovered, adding the new word into the basic dictionary to update the basic dictionary. The dictionary updating method and apparatus can reduce dictionary maintenance costs and improve dictionary update efficiency.

Description

technical field [0001] The invention relates to the field of intelligent interaction, in particular to a method and device for updating a dictionary. Background technique [0002] In many fields of Chinese information processing, it is necessary to complete corresponding functions based on dictionaries. For example, in an intelligent retrieval system or an intelligent dialogue system, through word segmentation, question retrieval, similarity matching, determination of retrieval results or intelligent dialogue answers, etc., each process is calculated by using words as the smallest unit, and the basis of calculation is Word dictionary, so the word dictionary has a great impact on the performance of the entire system. [0003] The progress and changes of social culture and the rapid development of economy and commerce often drive the change of language, and the most rapid manifestation of language change is the emergence of new words. Especially in a specific field, whether ...
